To all 1077107777.. it may concern: l

Be it known that 1', JAMES R. SHIRREFFB,

-al citizen of the United Statesresiding at Los Angeles. in the couty of Los Angeles and Sta-te of California, haveinvented new and useful Improvements in Universal Joints, of whichthe following is a specification.

This invention relates to universal bearings, and more particularlyto bearings adapted for supporting bracket lamps upon a vehicle, and the principal object is tov pro# vide a strong andeiicient joint with suitable friction disks so that the lamp supported lon'the bracket will have universal movementand be readily retained in any desired position to wh'ich'itmay be shifted.

. In the drawings accompanying this speci'- l cation and forming'therewith the application 'for Letters Iatent: Figure 1 is a'side elevation of a bracket showing the joint applied `thereto connected with an electric automobile lamp. Fig. 2 is a plan viewof the bracket, the 'joint end --being shown 1n section,i the lamp and its pivoted stud being removed.

More specifically in the drawings, 5 designates an angle bracket having a base plate 6 whichis provided Ywith suitable bores so that the same may be secured tothe body of the. vehicle or other object on which it is desired to secure the bracket, theouter end being provided with a bore in the head 7, the bore being preferabl in a plane par allel with the plane tow "ch the plate 6 is secured and of such size as to readily ref ceivethe cylindrical stud 8 formed on the swiveling member 9. This member also has a head 10'in which a bore is provided in a plane at right angles to the axialpla-ne of the cylindrical stud- 8 and interposed between these `two is a bearing flange 1 1. The

upwardly disposed end of the stud 8 is,

threaded and adapted to engage a, nut 12.-

is' preferably placed adjacent the -bea g liange 1,1 andv adapted to engage the. at face of one side of the head 7. A similar fiber washer or other suitable friction ma- :terial 15 is interposed between the metal washer 16 which is the nut 12 is secured on the .stud. l

. This fixturevis particularly adapted for placed. in position before Patented June 3o, 1914.

supporting electric headlights of the type 17 shown, which is provided with a supporting extension 18 having a fiat face projecting frame which has a-cylindrcal stud threaded Y on its free end-torceive a nut 20. This stud 19 isof such size that it fits Within the bore 21 in the head "10, and interposed 'between the face of the extension 18'in the head is a fiber washer 22,51 similar washer 23 being placed adjacent the metalwasher 24 to form a suitable bearing surface for this washer and the nut 20.

' In the operation of the device, by means of a Suitable handle shown at 25the lamp 17 may be turned readily in a universal -di- Y rection and willv remain in -this position without adjustment and without bein?` af- ,fected by the vibrations of the vehice to which it is ing.

vWhat I claim is: A universal swiveling joint, comprising a bracket member having an apertured head formed with flat parallel side faces, a swiveling member having an apertured head, an annular bearing ange, andl a cy'-, lindrical stud adapted to engage said aperture in said-bracket head, friction disks enapplied when the' latter is mov-1 gaging the side' faces of said head and encircling said stud, means to secure said stud in frictional engagement, member having a, flange, -a centrally disposed cylindrical stud adapted to bear with- 1n the aperture in said sw'iveling member, frictional plates to engage said head ofthe a supporting swiveling member, and'securing means to secure said supporting member in pivotal relation to said swivelmg member.

In witness that I Cnimthe' foregoing I' A have hereunto'subscribed my name this 14th In assembling the device a ber washer 14 day of May, 1913. JAMES R. SHIRREFFS.- Witnesses:
